S WEEP-RAKE PUSH.

Application. filed February 20, 1912.

To all whom it may concern:

Be it known that we, WILLIAM FLOYD RnsLnn and ()Lrvna PERRY RnsLnn,citizens of the United States, residing at Hendley, in the county ofFurnas and State of Nebraska, have invented certain new and usefulImprovements in Sweep-Rake Pushes, of which the following is aspecification.

(lur invention relates to that class of rakes in which the draft animalsare located behind the rake and which employ a push bar or sweep toclear the rake teeth of collected material when a sutl'icient amount hasbeen gathered and it is desired to withdraw the rake from under thecollected material.

T he object of our invention is to produce a push bar or sweep ofimproved construction and efliciency.

Figure 1 is a plan view of a push bar or sweep constructed in accordwith our invention, together with portions of a rake to which it isattached. Fig. 2 is a detail of an attaching bracket.

1, 1, is a pair of poles or tongues, 1 a rear transverse rake beam and 1a forward transverse rake beam, the construction of the rake beingimmaterial to the present invention with the exception that the teeth ofthe rake point in the same direction as the draft animals heads and thedraft animals are located behind the rake and travel forward with therake when the material is being collected and back with the rake whenthe rake is to be withdrawn from the material.

2, 2, are brackets of convenient shape, each bracket supporting. betweena pair of horizontal braces, a push lever 4i, pivotally secured near itsmiddle point to the braces by fastenings 5, the brackets being securedby fastenings (3 to the rear transverse rake beam and the forwardtransverse rake beam.

7 is a transverse push bar of convenient construction adapted to braceor support a construction 10 to prevent material from following the raketeeth as they are withdrawn. The transverse bar forms the front side ofa rectangular frame having side pieces 8 and rear piece 9 all braced andbolted together. The transverse bar is surmounted by a framework 10, ofsuitable design, adapted to serve as a barrier.

Near the inner end of each of the push levers t is a diagonally attachedbracket or strap iron 11 receiving one end of a push arm 12, the otherend of the push arm being Specification of Letters Patent.

secured at 13 to one of the side pieces 8 by means of a clevis or otherpivotal device it.

To a stud or hook 15 near the forward end of each of the push arms 12 issecured one end of a spring 16 the other end of the spring being securedto the forward end 17 of a double link or hook 18 located at the innerend of the adjacent push lever 4. To the rear end of each of said linksor hooks 18 is connected a rod 19 the two rods extending rearwardly andengaging a single ring 20 from which extends rearwardly two rods 21 eachleading to an eye bolt 22 secured to the inner end 23 of a rear or pulllever 24: pivoted at 25 to the rear end of one of the poles or tonguesl, the tongues being braced by a transverse beam 26, and each of therear r pull levers 2 carrying at its outer end a strap or pivotconnection 28 to which is attached a swingletree 27. The harness tracesof the draft animals may be attached to the swingletree and the polestraps to the ring 31.

29 are stops mounted on the connecting beam 26 each stop beingpreferably in the form of a J shapediron, the upturned end of whichserves to limit the backward movement of the inner end of the abuttingpull rod.

To the outer end of each of the forward or push levers 4 is attached arod connection 30 having a harness attaching ring 31 at its end andformed in two sections connected by links 32.

It will be readily seen that the draft animals pull the machine forwardby means of traces attached to the swingletrees 27 which by connections28 are secured to pull bars 24, which in turn are, by pivots 25,attached to the tongues or reaches 1. The inner ends of pull bars 24 areprevented from backward movement by back stops 29.

It is obvious that, when the rake has collected a. supply of material inthe usual manner, a backward movement of the animals will pull on theends of the forward or push levers 4 and pull on the inner ends of therear or pull levers 24. Thus the movement of the rake and all parts ofthe sweep, excepting the frames and diagonally inclined push arms 12, isreversed. The push arms of the forward or push levers, acting as a pairof lazy-tongs, hold the transverse push bar 7 and surmounting framework10 against the collected material.

As soon as the animals cease their backward movement the springs 16return the frame 10 to normal position, the duty of the springs beingprincipally to assist in moving the frame forward and taking up slack orlost motionand the ring 20 as an equalizer or synohronizer of themovements of the rods 19 and 21. By this arrangement the animals whenthe collecting process is going on hold the sweep frame back against therake frame and are assisted in the discharging process by the action ofthe springs, the springs thereby not adding to the power required tomove the rake, but assisting in {hedmovement of the rake away from theThe within described mechanism applies only to wheel rakes and no claimis made for its application to drag rakes.

Having thus described our invention the following is what we claim asnew therein and desire to secure by Letters Patent:

1. The combination with a push rake frame, of a push bar slidablethereon, draft animal operated means for actuating said push bar, andtension devices operatively connected with said bar and with said meansand assisting said push bar to discharge the load movements.

2. The combination with a push rake frame, of a push bar slidablethereon, draft levers pivoted on the frame and connected forsimultaneous movement, a rod connecting the bar with one of said leversand regulating the relative movement of the bar and lever, and a tensiondevice assisting said bar to discharge the load.

3. The combination with a wheeled frame, of a push rake including asupporting frame, a push bar slidable thereon, and means automaticallyoperated upon backward movement of said wheeled frame for actuating saidpush bar, said means including a pair of draft trees attached to saidframe, a pair of levers pivoted on said frame and connected to said bar,connecting rods for said levers and draft trees, and a spring for eachof said levers assisting said bar to discharge the load.

In witness whereof, we have hereunto affixed our signatures in thepresence of two subscribing witnesses.
